Title: Electric grill for foods
IPC: F24C7/06
Filed: 1967-08-01
Abstract: 1,149,586. Grilling oven. SOC. D'EMBOUTISSAGE DE BOURGOGNE. 1 Aug., 1967 [18 May, 1967], No. 35303/67. Heading F4W. [Also in Divisions A4 and H2] An electric grill comprises a lower and upper shell 1, 2, each containing a removably mounted heating resistor of the shielded type with spaced arms 3, 4 set in perforated plates 65, 66, wherein the internal diameter of shell 1 is slightly greater than the external diameter of shell 2 to allow frictionless engagement of the latter within shell 1. Shell 2 comprises two coaxial casing 6, 8 with dome-shaped end walls 10, 12 and parallel cylindrical side-walls 14, 16, terminating in opposite facing annular flanges 18, 20 so. that a channel is formed between them in which is fitted a silicone-rubber 0-ring 22. The said casings are joined together by a threaded rod 24 secured to the summit of the dome-shaped end-wall 10 and fitted with a nut 26 which is rotatably mounted on the dome 12 and secured to a control knob 28. A friction collar 30 allows rotational motion of the control knob with slight sliding friction against the casing 8. The end-wall 10 is so formed to have a chamber 32 with a perforated base 34 and a perforated detachable cover 36 into which is advantageously placed a bottom layer of powdered refractory material and an upper layer of activated charcoal to absorb fat and unpleasant odours from the vapours which then escape through vents 42. The arms 47, 48 of the heater element terminate in socket connectors 49, 50' which are removably mounted by engagement in bores 17 and 44, 46, and comprise a terminal protector 51, covered by an end cap 52, with interposition of a projecting annular ring seal 53, and two connector pins 54 which fit into corresponding plug connectors 57, 58. When plugs 61 are inserted into the corresponding sockets (49, 50), locking springs 55, comprising flexible rods having elbow heads mounted opposite to bores 56, project outward through the said bores thus locking the socket connectors inside the recesses and preventing them from being removed as long as the plug connectors remain in position. In use as an oven a removable grid is provided above element 3 to stand the food on and element 4 is maintained at a predetermined distance from the piece of food to be cooked by locking it in position by turning knob 28. This causes the closure of casings 6, 8 and hence of the flanges 18, 20 thus compressing seal 22 which then projects relatively to the wall 16 with the result that shells 1, 2 are brought into contact with strong friction and coupled together in an airtight manner. A run off cook for meat juices may be added to the annular trough 11, in which the juices are normally collected and prevented from burning by the relatively remote distance from heater element 3. In addition a support 69 at the ends of the elements remote from the arms 47, 48 preventing deflection of said arms and a thermostat or thermal safety system for the electric current supply may also be provided.

Abstract: 1494576 Cleaning sensors MEIDENSHA K K 27 Aug 1975 [6 Sep 1974 9 Sep 1974 31 Oct 1974 24 Dec 1974] 35384/75 Heading G1A, G1G and G1N A sensor which measures a property of a liquid in which it is immersed is periodically cleaned by turbulent flows induced by air bubbles injected into the liquid. The sensor is mounted in a casing and air bubbles are injected into the base of the casing so that they rise past the sensor and clean it. The sensor may measure dissolved oxygen, or turbulence by either light scattering or ultrasonic radiation. As shown in Fig. 3, sensor 32 is mounted in cylinder 26 which has windows in the area surrounding the sensor. Air supplied through pipe 70 emerges from holes 24a and the resulting bubbles rise past the sensor and are deflected out of the casing by deflector 28. In the embodiment of Fig. 13, air from pipe 70B emerges from holes 26F to clean the sensor and air from pipe 70A emerges from holes 26E and functions as a bubble lift pump creating a flow of liquid past the sensor. In alternative embodiments, the air bubbles may emerge from an outlet immediately below the sensor or may, in a sensor using radiation, emerge from adjacent both sides of a window. The sensor is preferably cleaned intermittently and between measurements. A shield may be provided on an upstream face of the casing to protect the sensor from solids in the liquid.

Title: Process for the production of polyesters and pure terephthalic acid
IPC: C08G63/78
Filed: 1960-10-18
Abstract: Partial copolyesterification with a polyhydric alcohol of a mixture of isomeric phthalic acids under an atmosphere of an inert gas is interrupted when the amount of water produced indicates that all of the isomers other than terephthalic acid have been esterified, the polyester separated by filtration from the residual terephthalic acid and further polycondensation is preferably effected.  The polyhydric alcohol may be dihydric, in which case the further polycondensation gives (a) a saturated copolyester, using optionally a fatty acid or (b) an unsaturated copolyester, using maleic and/or fumaric acid and optionally a saturated acid followed by reaction with a cross-linking monomer. The further condensation in case (b) may be carried out in presence of the same or a different dihydric alcohol. Alternatively, where the polyhydric alcohol is trihydric, the separated product may be further condensed with one or more saturated and/or unsaturated monocarboxylic fatty acids to obtain a copolyester resin, e.g. a glycerophthalate when glycerol is used.  In Examples:- (1) and (2) the partially copolyesterified product from iso- and tere-phthalic acids and propane-1:2-diol was further reacted with propane-1:2-diol and maleic acid or anhydride and the product was polymerized with added styrene; (3) as in (2), the starting material containing also orthophthalic acid; (4) as in (2) except that in the first stage ethylene glycol was used instead of the propanediol; (5) as in (2) the starting material being ortho- and tere-phthalic acids; (6) the partially copolyesterified product from iso- and tere-phthalic acids and propane-1:2-diol was further reacted in presence of adipic acid; (7) the intermediate from ortho- and tere-phthalic acids and glycerol was further reacted with linseed oil acids.ALSO:Pure terephthalic acid is isolated from a mixture with at least one of the other phthalic acids by partial copolyesterification p  with a polyhydric alcohol under an atmosphere of an inert gas, stopping the reaction when the amount of water produced indicates that all of the isomeric acids other than terephthalic have been esterified and then separating by filtration the residual terephthalic acid from the esterified product.

Filed: 1932-12-20
Abstract: 395,938. Control of several motors. SCHLOEMANN AKT.-GES., 13, Steinstrasse, Diisseldorf, Germany. Dec. 20, 1932, No. 36126. Convention date, March 5. [Class 38 (iii).] In a continuous wire rolling mill with groups of rolls the driving motors of one group, e.g. 3 are arranged for coupled three phase' working or independent and individual direct current working so that with D.C. working, group 3 rolls can be used as the finishing stage of rolling small iron bars. To keep the rolls up to speed in this case the bars initiate a known relay mechanism which effects a voltage regulator or field regulator 21 of each motor, as follows. With the 3-phase coupling switches 15 open, a bar going through the pass X of the first roll stand 3 closes a switch 16 which actuates a magnetic clutch 19 and current relay 22. Clutch 19 couples cam shaft 18 to the drive of the rolls stand through bevel gears so that one of the cams operate a switch 23 which open one of the switches 20 to connect a rheostat 21 in series with the shunt field of the first motor 14, the rheostat 21 being so adjusted for each kind of metal that the roll motor speed is practically constant between no load and full load. The cam shaft 18 makes one complete revolution, thus putting a shunt rheostat in circuit in each of the motors 14 after which it is stopped by the limit switch 24. If a second bar goes through the inill parallel with the first bar, e.g. at pass Y, it actuates a second magnetic clutch 19 which similarly puts in a second rheostat in the shunt of each of the motors parallel with the first rheostat, and so on for each bar passing through. The switch 16a maintains the motor windings as set for the Toll loads until the bar or bars has passed through the mill.

Abstract: 632,803. Photographic copying cameras TRIGGS, W. W. (Diebold, Inc.). Dec. 6, 1946, No. 36182. [Class 98 (i)] A copying camera having a lens mounted with its optical axis perpendicular to its object plane is characterized in that reflecting members, some locatable across said optical axis and others co-operating therewith, are provided for deflecting the light beam away from and back to the optical axis for varying the length of the light path between said lens and its object plane while lens and object plane remain relatively fixed. As shown, the invention is applied to a copying camera of the type described in Specification 617,603. Film 22 from a reel 23 is driven around a transparent rotatable drum 21 by rollers 25, 26, against which the film is pressed by spring-urged rollers 24, 27, to a takeup reel 28. Documents 16 placed on a table 15 are fed across a copying gate, illuminated by lamps 60, by power-driven belts 11 aided by idler belts 13, 14 in contact with belts 11, and are copied by means of a lens 18 through a slit 20 extending across the film. To compensate for the lens 18 having a focal length different from that for which the film and beltdriving means are designed, the length of the light path 58, 61, 62, 63, 59 between the lens and the document copying gate is made adjustable, an extension tube 31 containing reflectors 41, 42 being rack-and-pinion connected to an outer concentric part 32 of the side branch 30 of the light-tight tube 29 in which are situated two stationary reflectors 39, 40, mounted on members 48 which, when hinged covers 55 have been swung away upwardly, may be swung out of the light path for cleaning or if a low reduction ratio is desired. Means are provided for fine adjustment of the positions of the reflectors. The reflectors 41, 42 may be mounted similarly to the reflectors 39, 40.
